Dry Type Transformer
The safest choice for indoor power distribution. Air-cooled, oil-free transformers designed to eliminate fire hazards and minimize maintenance. Available in Cast Resin (CRT) and VPI technology.
What It Does
Traditional transformers use oil for cooling, which poses a risk of leakage or fire. **Dry Type Transformers** use air for cooling and solid insulation materials.
Why choose Dry Type? They are self-extinguishing and non-explosive. This makes them the only safe option for indoor installations in basements, hospitals, and high-rise commercial buildings.
Technology & Construction
We offer two specific technologies based on your environmental needs:
Key Features
100% Fire Safe
No flammable liquids. Self-extinguishing insulation prevents fire spread.
Eco-Friendly
No risk of oil spills or soil contamination. All materials are recyclable.
Low Maintenance
No oil level checks, no leakage repairs, and no sludge testing required.
High Overload Capacity
Handles short-term overloads better than oil types due to high thermal mass.
